As shown in FIG. 1, weirs are provided in the river 1.
There is a place where 9 is constructed, and a place where a plurality of branch flow paths 2, 10 and 11 which communicate between the upstream part and the downstream part of the weir 9 are formed. Some of the multiple branch flow paths

As a form of the water turbine 3 and the compressor 5 suitable for the above-described flowing water air energy system, the inventors of the present invention arrange them in the flowing water of the branch flow passage 2 as shown in FIGS. 3 (a) and 3 (b). Compressor 50 capable of adjusting the amount of compressed air generated according to the rotational torque obtained by the turbine 20
We propose a combined form.

This water turbine 20 is shown in FIGS. 3 (a) (b) and 4 (a) (b).
As shown in FIG. 5, an output shaft 21 rotatably disposed on the frame 18 via a bearing 19, and disks 22, 23, 24, 25 as extending portions extending in the radial direction of the output shaft 21. , A plurality of wing members 26 disposed at equal intervals in the circumferential direction between the respective disks 22, 23, 24, 25 in parallel to the axial direction of the output shaft, and an elastic support mechanism 27 for elastically supporting the direction of the wing members 26. It has and.

As shown in FIGS. 5 (a) and 5 (b), the wing member 26 has a structure in which a plurality of (for example, three) action surfaces 31 are connected by a rotary shaft 32. The rotating shafts 32 are provided on both upper and lower sides along an axial axis L2 that is deviated from the axial axis L1 passing through the centroid X of the working surface 31 by a predetermined distance in the width direction.

The wing member 26 is mounted on the rotary shaft 32 with a slide bearing (not shown) consisting of a split ring, and the disks 22 and 2 are
Rotating shafts 32 are mounted in mounting holes formed in 3, 24, 25 at equal intervals in the circumferential direction, and mounted on the disks 22, 23, 24, 25. As a result, the working surfaces 31 of the wing members 26 arranged between the disks 22, 23, 24, 25 are oriented integrally in the same direction.

As shown in FIGS. 4 (a) and 4 (b), the wing member 26 is elastically supported in its rotation by an elastic support mechanism 27 mounted on the uppermost disc 22. In a state where there is no water flow, each working surface 31 of the wing member 26 is set so as to be arranged along the circumferential tangential direction with the normal line as the axis and the working surface.
When the energy of the flowing water in the branch flow passage 2 is received by 31 the working surface 31
The angle of is adjusted.

The elastic support mechanism 27 has one end attached to a predetermined position of the disk 22 and the other end attached to the rotary shaft 32 of the wing member 26, and an air cylinder 28 (air cylinder) that elastically supports the rotation of the wing member 26. Spring). The elastic support mechanism 27 can be released from the elastic support state by releasing the air from the air cylinder 28. If the air is supplied to the air cylinder 28 after the elastic support state is released, the elastic support mechanism 27 operates. The elastic support state can be restored. In addition, 29 in the drawing of FIG. 4A is an intake supply port for supplying air to the air cylinder 28.

In the water turbine 20, due to the action of the elastic support mechanism 27, when there is no water flow, the action surface 31 of the wing member 26 is centered on the axis of the output shaft 21, as shown in FIG. It extends along the circumferential tangent of a circle C1 having a radius in the radial direction from the axis to the rotation axis L2 of the wing member 26. When there is a water flow, as shown in FIG. 7, the reaction force (F1 to F6) mainly due to the action surface 31 of the wing member 26 changing the water flow.
The blade member 26 rotates about the rotation shaft 32 as the rotation center (L2). The inclination of the wing member 26 depends on the moment generated at the rotation center (L2) of the wing member 26 due to the action of water and the wing member 26.
Is determined to be a tilt that balances with the moment generated at the rotation center (L2) of the wing member 26 by the elastic reaction force of the air spring 28 that is extended by tilting toward the inner diameter side or the outer diameter side. The hydraulic force acts in a direction perpendicular to the acting surface of the wing member 26, with the centroid X (L1) of the acting surface 31 of the wing member 26 as the action point of the hydraulic force. Further, in the circumferential direction, the side of the rotary shaft (L2) of the wing member 26 where the hydraulic force acts is always on the rear side in the rotational direction of the hydraulic turbine. Further, the water turbine 20 is also caused by the water flow flowing outward from the cylindrical region surrounded by the wing members 26.
A torque in the rotation direction can be obtained, and in the rotation direction at that time, the side on the hydraulic force acting point is behind the rotation axis of the wing member 26 in the circumferential direction.

The inclination of the wing member 26 is such that when the wing member 26 moves in the advancing direction of the flow of water, more energy of the running water can be obtained, and the wing member 26 is not affected by the flow of water. The resistance becomes smaller when moving in the opposite direction. Therefore, even if the water turbine 20 is arranged in running water, the resistance is small, and therefore, as shown in FIG.
The wing members 26 can be installed in the running water of the branch flow path 2 in a state where each wing member 26 is immersed in the running water so that the blades are orthogonal to the flow direction of water. The turbine 20 receives the energy of flowing water on the working surface 31 of the wing member 26, the output shaft 21 rotates in a fixed direction, and the rotation torque can be output from the output shaft 21. . According to this water turbine 20, since the wing member 26 receives little resistance from water, as shown in FIG.
Since 20 can be installed in a state of being completely submerged in running water, the installation space on land can be reduced.

The output shaft 21 of the water turbine 20 has a first power transmission shaft 37 of the branch flow passage 2 via a first gear 36, as shown in FIG. 4 (a).
It is designed to transmit rotational torque to. The rotation torque transmitted to the first power transmission shaft 37 is, as shown in FIG. 3A, a second power transmission shaft 39 and a third power transmission shaft 40 which are horizontally arranged via a second gear 38. Be transmitted to. A disc brake 41 is attached to the tip of the second power transmission shaft 39. The disc brake 41 is used for decelerating and stopping the water turbine 20. For example, when the turbine 20 is maintained, the disc brake 41 can stop the turbine 20 to ensure the safety of the maintenance work. Further, even if the rotation of the water turbine 20 becomes too fast, the rotation speed can be reduced by the disc brake 41.

The third power transmission shaft 40 is adapted to transmit the rotational torque to the fourth power transmission shaft 43 via the conduction of the belt 42. This belt transmission mechanism transmits rotational torque from the third power transmission shaft 40 to the fourth power transmission shaft 43, and
It has a function as a transmission for changing the rotation speed. The rotational torque is from the fourth power transmission shaft 43 to the fifth power transmission shaft 43.
It is adapted to be transmitted to the drive shaft 51 of the compressor 50 via 44.

Next, the compressor 50 suitable for use in the flowing water air energy system will be described.

The cylinder head of the cylinder body 54 of each operating cylinder 53 is formed with an intake port 57 for intake of outside air and an exhaust port 59 of compressed air communicating with a compressed air chamber 58 for storing compressed air. The inlet 57 and the outlet 59 are provided with an intake valve 60 and an exhaust valve 61, respectively.

The intake valve 60 is an automatic valve that is pushed open by the outside air pressure. The shaft portion 60a is directed to the outside of the cylinder body 54 in parallel with the cylinder axis L, and the valve portion 60b is attached to the valve seat provided inside the cylinder head. And a spring seat 60c is provided at the other end of the shaft portion 60a penetrating outside the cylinder head.
The valve spring 60d is mounted between c and the outer surface of the cylinder head while being elastically compressed.

Since the internal pressure of the cylinder main body 54 of the intake valve 60 decreases during the intake stroke while the piston 55 moves from the top dead center to the bottom dead center, the intake valve 60 is pushed open by the external atmospheric pressure to open the outside air inside the cylinder main body 54. Inhale. During the exhaust stroke while the piston 55 moves from the bottom dead center to the top dead center, the air in the cylinder body 54 is compressed and becomes higher than the outside air, so the intake valve 60 is pushed up by the internal pressure in the cylinder body 54. Close the intake port 57.

A recess 55a is formed in the piston head of the piston 55 so as not to interfere with the valve portion 60b of the intake valve 60 in the cylinder at the top dead center.

The exhaust valve 61 is an automatic valve that is pushed open by a predetermined compressed air pressure, and is arranged in parallel with the cylinder axis L and the cylinder body 5
A valve portion 61b is provided on a valve seat provided on the outside of the cylinder head with the shaft portion 61a facing the outside of 4, and a spring seat 61c provided on the outer surface of the valve portion 61b and a compressed air passage for the cylinder head. Five
The valve spring 61d while being elastically compressed between the inner surface of 9 and
Is installed.

Since the internal pressure of the cylinder body 54 of the exhaust valve 61 is low during the intake stroke while the piston 55 moves from the top dead center to the bottom dead center, the valve spring 61d acts to close the exhaust port. To do. In the exhaust stroke during which the piston 55 moves from the bottom dead center to the top dead center, when the air inside the cylinder body 54 is compressed and becomes higher than a predetermined pressure, the valve spring 61d is compressed by the internal pressure and the exhaust valve 61 is opened, and the air compressed in the cylinder body 54 is exhausted from the exhaust port.

An actuator 63, which operates according to a signal from the control device 62, is attached to the exhaust valve 61. This actuator 63 can pull the exhaust valve 61 outward according to a signal from the control device 62 and maintain the exhaust valve 61 in an open state. When the exhaust valve 61 is opened by the actuator 63, its operating cylinder
In 53, the piston 55 only idles and compressed air is not generated.

The pistons 55 of the left and right working cylinders 53 are
Are connected by connecting rod 56, but this connecting rod 56
In order to absorb a mounting error and a shake during operation, a flexible connecting rod having a connecting pin attached to an intermediate portion may be adopted.

In the crank mechanism 52, as shown in FIGS. 9 and 10, a vertical bisector drawn from the cylinder axis L of the two working cylinders 53 is used as a center line T of the crank mechanism 52, and this center line T is used. A cylindrical casing 71 arranged as the center
And a first gear 73 as a rotating member rotatably supported in a casing 71 by a bearing 72, and a second gear 77, which will be described later, penetrates into a position eccentric from a center of the first gear 73 by a pitch circle radius r1. A planet shaft 76 rotatably mounted in the hole 74 through a bearing 75, a second gear 77 as a planet gear fixedly mounted to one end of the planet shaft 76, and the other end of the planet shaft 76 ( A balancer 78 formed on the connecting rod 56 side) and a connecting pin 80 that connects the connecting rod 56 via a bearing 79 are provided.

As shown in FIG. 10, a drive shaft 51, which receives the rotational torque from the water turbine 20 and rotates, is disposed below the first gear 73. The first gear 73 meshes with the third gear 83 attached to the drive shaft 51,
3 It receives rotation torque from gears and rotates. The second gear 77 is the
The planetary shaft 76 pivotally supported by the first gear 73 revolves with the rotation of the first gear 73, and also meshes with an internal gear 84 fixedly arranged on the inner peripheral surface of the casing 71 to rotate on its axis.

The pitch circle radius r1 of the second gear 77 and the internal gear 84
The relationship with the pitch circle radius r2 is r1: r2 = 1: 2, and the connecting pin 80 formed on the planet shaft 76 is connected to the pitch circle radius r1 of the second gear 77 from the center of the planet shaft 76. They are provided at the same distance and are connected to the connecting rod 56 via a bearing 79. A flywheel 85 is attached to the drive shaft 51 so that inertial force during rotation can be stored.

With the above structure, a mechanism for linearly reciprocating the connecting pin 80 and the connecting rod 56 is formed. That is, the crank mechanism 52 includes the drive shaft 51 that rotates by receiving the rotational torque from the water turbine 20, the third gear 83, and the first gear 83.

The control device 62 comprises a detector for detecting the rotational speed of the water turbine 20 and a controller for sending a signal for operating the actuator 63 according to the rotational speed of the water turbine 20. Control device
In a predetermined calculation process in the control unit, when 62 detects that the rotational speed of the water turbine 20 is lower than the predetermined rotational speed (in other words, the rotational torque obtained by the water turbine 20 from the water flow is reduced. In this case, the number of working cylinders 63 that generate compressed air is reduced to reduce the resistance of the compressor 50 and reduce the load on the turbine 20 so that the turbine 20 rotates at an appropriate rotational speed. On the contrary, when the rotational torque obtained by the water turbine increases, the working cylinder 63 that generates compressed air
The number of can be increased.

Specifically, the obtained hydraulic power is reduced, and
When the number of revolutions of 20 becomes lower than a predetermined number of revolutions, among the plurality of working cylinders 53 that generate compressed air, the actuators 63 of some of the working cylinders 53 are actuated to cause the working cylinders 53 to operate. The exhaust valve 61 of the above is left open, and the piston 55 of the working cylinder 53 is idled,
The resistance of the entire compressor 50 is reduced, and the turbine 20 is set to an appropriate rotation speed. On the contrary, when the obtained hydraulic power increases and the rotational speed of the water turbine 20 becomes higher than the predetermined rotational speed, some of the operating cylinders 53 among the operating cylinders 53 that are idling due to the operation of the actuator 63. The actuator 63 is stopped to allow the exhaust valve 61 to function normally, and this operating cylinder 53 is operated, and the number of operating cylinders 53 that generate compressed air is increased to increase the overall resistance of the compressor 50.
This resistance lowers the rotation speed of the water turbine 20 to an appropriate rotation speed.

That is, the control device 62 operates cylinder 53 for generating compressed air according to the rotational torque obtained by the water turbine 20 so that the rotational speed of the water turbine 20 is always within a predetermined proper rotational speed range. Are adjusting the number of.

It is possible to operate while maintaining a proper rotation speed. Although the exhaust valve 61 is provided as the actuator in the above embodiment, the intake valve 60 may be provided with the actuator.

The preferred embodiments of the water turbine and the compressor of the present invention have been described above, but the present invention is not limited to the above.

For example, in the above-mentioned water turbine 20 as well, the disks 22, 2
On the side where the wing members 26 attached to 3, 24, and 25 go counter to the flow direction of the water, there is a problem that the energy loss of the flowing water is large because it receives resistance from the flow of water. Therefore, as a means for solving such a problem, as shown in FIG.
On the side where 26 flows in the direction opposite to the flow direction of water, a rectifying member 90 that blocks the flow of water may be attached so that the water flow does not directly hit the wing member 26. According to this rectifying member 90, since the water flow does not directly hit the wing member 26 on the side where the wing member 26 goes backward in the water flow direction, the resistance received when the wing member 26 goes backward in the water flow direction is reduced. To be done. Further, the rectifying member 90, as shown in the figure, on the upstream side of the water turbine 20, the flow of water,
It is desirable that the wing members 26 flow from the side that is backward in the flow direction of water to the side that the wing members 26 are forward in the flow direction of water. According to the rectifying member 90, the resistance that the wing member 26 receives from water is reduced on the side that runs counter to the flow direction of water, and the rotational torque that is obtained from water on the side where the wing member 26 runs in the flow direction of water is obtained. Is larger, the energy recovery efficiency of the flowing water can be further improved. In addition, this rectifying member 90
Also has the effect of increasing the flow velocity of the flowing water and increasing the energy obtained from the flowing water.

Although the water turbine 20 uses an air spring composed of an air cylinder as the elastic support mechanism, the elastic support mechanism is not limited to this. Further, the water turbine 20 has been described as one in which the rotation angle of the wing member is adjusted by the elastic support mechanism, but the water turbine is not limited to this.

As another form of the water turbine, as shown in FIGS. 12 and 13, it is possible to employ a water turbine that mechanically controls the rotation angle of the wing member by a chain mechanism.

As shown in FIG. 13, the water turbine 100 includes an output shaft 101 and an extending portion 102 extending from the output shaft 101 in the radial direction.
103, a fixed sprocket 104 fixedly disposed on a frame body on which the output shaft 101 is axially supported, and the output shaft 101 between the extending portions 102 and 103.
Plural (for example, four) wing members 105 provided with a rotation axis in parallel with
a to 105d, planetary sprockets 106a to 106d provided on the rotating shafts of the respective wing members 105a to 105d, and a chain 10 wound between the fixed sprocket 104 and the planetary sprockets 105a to 105d.
7 and.

Fixed sprocket 104 and planet sprocket 1
The radius of 06a to 106d is set to 1: 2, and the output shaft 101
When the wing members 105a to 105d revolve once, the chain 107 wound between the fixed sprocket 104 and the planetary sprockets 106a to 106d causes the wing members 105a to 105d to move in the direction of rotation of the output shaft 101. Is designed to rotate half a revolution in the opposite direction.

For example, as shown in FIG.
The output shaft 101 is rotatably supported by a frame fixed to the branch flow path 2 so as to be orthogonal to the flow of water. Then, the wing member 105a located on the upstream side with respect to the water flow is installed in a state of being rotated by 45 ° in the clockwise direction from the direction parallel to the water flow direction, and is positioned in the clockwise direction forward from the wing member 105a. Rotate the wing member 105b 90 ° clockwise from the water flow direction.
In a rotated state (so that it is orthogonal to the flow of water)
Feather member 105c installed and located downstream of the water flow
Is installed in a state of being rotated by 135 ° in the clockwise direction from the flow direction of water, and the wing member 105d located in front of the wing member 105c in the clockwise direction is installed parallel to the flow of water.

In this water turbine 100, the output shaft 101 is set to 1 clockwise.
When rotated, each of the wing members 105a to 105d is adapted to rotate counterclockwise, and in the state shown in FIG. 12, each of the wing members 105a to 105c receives hydraulic force to output the output shaft.
It is designed to obtain a clockwise rotation moment in 101. Further, as in the wing member 105d in the same figure, at a position that is backward in the flow direction of water, the wing member 105d is close to being parallel to the flow of water, and therefore the resistance received from water is small. By adopting this water turbine 100 in the above-described flowing water air energy system, it is possible to efficiently obtain the rotational torque from the energy of the flowing water to operate the compressor.

Next, a modified example of the water turbine 100 will be described.

As shown in FIGS. 14 and 15, this water turbine 120 employs a planetary gear mechanism instead of a belt mechanism as a control means for the wing member 105. This turbine 120 is shown in FIG.
As shown in 5, an output shaft 121, extending portions 122 and 123 extending from the output shaft 121 in a radial direction, and a fixed gear 124 fixedly arranged on a frame body on which the output shaft 121 is axially supported. , A plurality of (for example, four) wing members 125a to 125d provided by disposing a rotating shaft between the extending portions 122 and 123 in parallel with the output shaft 121, and the wing members 125a to 125d.
The planetary gears 126a to 126d provided on the rotating shaft of the
2 includes a fixed gear 124 and a counter gear 107 which is arranged so as to mesh with the fixed gear 124 and the planet gears 125a to 125d.

This turbine 120 also has a fixed gear 124 and a planetary gear 126a.
When the number of teeth of ~ 126d is set to 1: 2, the output shaft 121 makes one rotation, and the wing members 125a to 125d revolve once, the counter gear 127 between the fixed gear 124 and the planetary gears 126a to 126d. As a result, the wing members 125a to 125d rotate about a half rotation in the direction opposite to the rotation direction of the output shaft 121, and the same operation as the water turbine 100 is performed. Therefore, the above-mentioned water turbine 120 can be adopted as the water turbine of the flowing water air energy system of the present invention.

The turbine 100 and the turbine 120 described above may be configured such that the timing of rotation of the wing member with respect to the timing of revolution of the wing member may be slightly delayed or slightly advanced from the above.
